What is a HEIF file?
HEIF – High Efficiency image file. HEIF is the container behind HEIC: it can hold pictures compressed with HEVC (the files iPhones save, usually named .heic) or other codecs. Converting gives a picture every program can open.

ICO – Windows icon. ICO is the Windows icon format. One file holds the same picture in several sizes, each at most 256 × 256 pixels; browsers also use it for the small icon on a tab (the favicon).

- Photos from an iPhone keep their orientation: pictures are turned upright as the camera recorded.
- Tick Remove metadata in Options to leave out information stored in the picture, such as the camera and the place.
Frequently asked questions
Is converting HEIF to ICO free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my HEIF pictures uploaded anywhere?
Pictures up to 200 MB never leave your device: ConvertKitty converts them inside your browser, with ImageMagick compiled to WebAssembly. Only larger files, or formats your browser cannot handle (camera RAW, PostScript, XPS, LibreOffice and Publisher files, and video or audio), are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.
How large can the HEIF file be?
Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.
Can I change the size or quality of the ICO?
Yes. Click Options next to the file to set a width and height, choose a quality, remove metadata and more. Only the settings that make sense for HEIF to ICO are shown.
Can I convert several HEIF files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
